OBJECT: Skull base meningiomas carry a non-negligible risk of recurrence. In particular, those arising from the sphenoid wings or middle cranial fossa penetrate into extracranial regions, uncommonly showing massive expansion into the craniofacial regions on recurrence. The role of endoscopic endonasal surgery for those intractable lesions remains unclear. METHODS: We performed endoscopic endonasal craniofacial surgery for 8 recurrent meningiomas invading into the pterygopalatine fossa, infratemporal fossa, nasopharynx, paranasal sinus, or orbit, comprising 2 meningothelial and 1 fibrous meningiomas (WHO grade I), 3 atypical and 1 clear cell meningiomas (grade II), and 1 anaplastic meningioma (grade III)...

Primary liver cancer-including hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC)-incidence is increasing and is an important source of cancer-related mortality worldwide. Management of these cancers, even when localized, is challenging due to the association with underlying liver disease and the complex anatomy of the liver. Although for ICC, surgical resection provides the only potential cure, for HCC, the risks and benefits of the multiple curative intent options must be considered to individualize treatment based upon tumor factors, baseline liver function, and the functional status of the patient...

INTRODUCTION: The practice of positioning patients' arms above the head during catheter-injected hepatic arterial phase cone beam CT (A-CBCT) imaging has been inherited from standard CT imaging due to image quality concerns, but interrupts workflow and extends procedure time. We sought to assess A-CBCT image quality and artifacts with arms extended above the head versus down by the side. METHODS: We performed an IRB approved retrospective evaluation of reformatted and 3D-volume rendered images from 91 consecutive A-CBCTs (43 arms up, 48 arms down) acquired during hepatic tumor arterial embolization procedures...

Pulmonary embolism (PE) is usually caused by thrombosis or tumor. We report the long-term survival of a patient with PE due to a leiomyosarcoma in the deep vein. A 71-year-old woman complained of dyspnea and swelling of the left lower limb. Computed tomography revealed filling defects in the pulmonary arteries and deep vein. She was diagnosed with PE caused by venous thrombosis and treated with anticoagulant therapy. Her symptoms were prolonged, and D-dimer tests remained negative. Biopsy of the substance in the deep vein revealed leiomyosarcoma...

Cardiac papillary fibroelastoma is a rare benign cardiac tumor that represents less than 10% of all cardiac tumors. Most papillary fibroelastomas are relatively small. Symptoms, if present, are due to flow obstruction or peripheral embolization. The most common sites of origin are aortic and mitral valve surfaces. We present successful surgical resection of a papillary fibroelastoma through the mitral valve which originated from the posterior papillary muscle of the left ventricle.

This article is the first description of a spontaneous hepatic rupture in a young bodybuilder with a history of clenbuterol and ephedrine alkaloid use. The patient presented with a sudden mid-epigastric pain and vomiting. Hemoglobin levels decreased a few hours later and a computed tomography scan was performed which revealed a rupture of the right liver capsule and hemoperitoneum. Two attempts at transarterial embolization did not control the bleeding and a right hemihepatectomy was performed. The pathological report identified a hepatic adenoma, a capsular tear and diffuse peliosis hepatis...

Background: Portal vein embolization (PVE) is used preoperatively in patients to increase future remnant liver volume (FRLV). Unfortunately, some patients are found to be unresectable at exploration due to tumor progression or new lesions. The aim of this study is to evaluate the long-term effects of PVE in the embolized liver lobe when left unresected. Methods: Of 85 patients who underwent right PVE, 16 (19%) were unresectable (PVE-group). These patients were compared with 48 randomly matched patients from a pool of 75 unresectable patients who had not undergone PVE...

This report describes an atypical case of non-bacterial thrombotic endocarditis in a mitral valve. The patient suffered repeated embolism after achieving remission of Crohn's disease in the acute phase. Echocardiography revealed mitral valve leaflet and subvalvular thickening. Initially, this was considered indicative of infective endocarditis or a cardiac tumor; however, pathology and laboratory examinations showed non-bacterial thrombotic endocarditis without antiphospholipid syndrome or a malignant tumor...

BACKGROUND: Renal arteriovenous malformation is an aberrant vascular connection between the renal artery and vein. Acquired renal arteriovenous malformation (arteriovenous fistulae) accounts for approximately 70% of renal arteriovenous abnormalities. Congenital renal arteriovenous malformation, relatively rare, can result in significant hematuria which may require arterial embolization or nephrectomy. CASE PRESENTATION: A 64-year-old Asian man presented to the Urology department in our hospital with gradual left scrotal swelling for 2 years...

The most common primary cardiac tumor is myxoma, typically originating in the left atrium. Emboli to the central nervous system can cause cerebral infarction or, rarely, seed tumor growth within vessel walls, causing myxomatous aneurysms. Fewer than 60 myxomatous aneurysms have been reported, including 2 cases in children. Here, the authors describe 2 different growing myxomatous aneurysms in a child successfully managed using a combined multidisciplinary approach. A 12-year-old boy developed a sudden headache, diplopia, gait instability, and speech difficulty...

Nested stromal-epithelial tumor (NSET) is a non-hepatocytic and non-biliary tumor of the liver consisting of nests of epithelial and spindled cells with associated myofibroblastic stroma and variable intra-lesional calcification and ossification, which represents a very rare and challenging disease. Most of the reported cases have been treated with surgery, obtaining a long survival outcome. Here, we report the case of a 31-year-old Caucasian man who underwent surgery at our institution for a large, lobulated, multinodular mass of the right hemi-liver...

BACKGROUND: The recurrence rate of chronic subdural hematoma (CSDH) after trepanation is relatively high, and involves various factors. We encountered an extremely rare case in which metastasis of an extracranial malignant tumor to the hematoma capsule was thought to be causing short-term repeated recurrences of CSDH. CASE DESCRIPTION: The patient was a 74-year-old man who had undergone burr-hole evacuation of left CSDH 7 months earlier and had been receiving chemotherapy for stage IV gastric cancer for the preceding 6 months...

Pheochromocytomas are rare neuroendocrine tumors, with published incidence of 2 to 8 cases per million patients per year. The extension of these tumors into the vena cava and right atrium is rarely seen. Transesophageal echocardiography may be invaluable to delineate tumor extent and characteristics, which in turn may provide a useful tool to guide intraoperative surgical approach to these uncommon masses. In the case presented in this article, we describe the role of transesophageal echocardiography in guiding a safe and complete, excision of an invasive pheochromocytoma without embolization of tumor components...

Cardiac hemangiomas are rare benign tumors. Here, we report the case of a man in his 30s who had a cardiac hemangioma with no symptoms. He was being treated with β-blockers for chronic heart failure with hypertensive heart disease at Osaka Minato Central Hospital. Routine echocardiography revealed a mobile spherical mass in the left ventricle that had not been detected on echocardiography performed 4 months previously. Subsequently, the tumor was excised to prevent potential embolic events and was pathologically diagnosed as a cardiac hemangioma...
